Pre-compression A site is pre-loaded by means of a surcharge or by lowering the groundwater level, causing the ground to consolidate. After restoring original stress levels, the future structures built on this site settle less than those on the untreated ground.
This technique is used for cohesive soils. Consolidation of these soils is a long-term process, unless the existing longest drainage path is shortened by installation of sand drains or geo-composite drains.
Explosion Explosives are detonated on the surface in an array of boreholes, causing loose soil structure to become denser. The final density may not be achieved immediately as the dissipation of excess pore pressure generated may take some time.click here to continue read
